Phil Rogers of the Chicago Tribune reports the Cubs are calling up shortstop Starlin Castro and plan on inserting him into the lineup immediately.The 20-year-old is hitting .376 with one homer, 14 extra-base hits and 20 RBI in 26 games with Double-A Tennessee.

The same report suggests that eventually, it's likely the swap for Bradley will be one-for-one between the Rays and the Cubs. The Cubs would get Burrell in that scenario.
